4 Claims.

This invention relates to improvements in oil cans.

One object of the invention is to provide an oil can, such as the hand oilers generally used in oiling bearings and other wearing parts of machines, with means which will eiectively prevent the overflowing of the oil holes, with the accompanying waste of oil.

A further object of the invention is to provide an oil can having means positioned adjacent the free end of the discharge spout which will form a seal around the oil opening of the bearing or part being lubricated whereby upon the manual depression of the can bottom in the usual manner, the oil will more effectively be forced into the opening and parts to be lubricated.

Other objects of the invention relate to features of construction and arrangement of parts which will be apparent from a consideration of the following speciiication and accompanying drawing, wherein:

Figure l is an elevation of a conventional oil can having one embodiment of my improvements in position thereon.

Figure 2 is a broken View of the discharge end of an oil can spout illustrating the sealing member in section thereon.

Figure 3 is a sectional View taken on line 3--3 of Figure 2.

Figure 4 is a View partly in section illustrating the improvements in use.

Figure 5 is a broken longitudinal sectional view of the discharge end of an oil can spout illustrating a modified construction.

Figure 6 is a longitudinal sectional view of a further modiication shown in position on an oiler spout.

In the drawing, It is a conventional oil can or hand ciler, having a discharge spout I I. Adjacent the free end i2 of the spout is an annular seat i3 which may be formed of metal or other suitable material, and is pressed on or otherwise attached to the spout il. The seat I3 may have a marginal flange I4 at its forward end as illustrated in Fig. 2, for assisting in supporting a gasket or sealing member I 5. The sealing member i5, as well as those hereinafter described, may be formed of any suitable material such as felt, cork, rubber, leather or the like.

The sealing member l5 is of annular shape and, as illustrated, the end i2 of the spout preferably projects a short distance therethrough. When the oil can is inverted in use, as illustrated in Fig, 4, the end I2 is inserted into the oil hole I6 until the sealing member It contacts firmly with the part of the device in which the hole is formed. The sealing member being preferably of yielding material forms a seal between the spout il and the part being lubricated, and as the bottom of the 'can iii is depressed in the usual 5 manner to discharge the oil, the latter cannot flow upwardly from the hole i6 and go to waste. The slight pressure exerted by the user in depressing the bottom of the can acts on the oil to force it into the oil hole and to the parts to be 10 lubricated. The oil can thus acts as a low pressure lubricating device and prevents the excessive loss of oil by preventing the overflowing of the same from the oil holes.

The form of the invention shown in Fig. 5, 15 differs from that shown in Figs. l and 2 in that the spout is provided with an integral annular seat il which supports the sealing member I5.-

In the form of the invention illustrated in Fig. 6, the seat i8 is slidable on the spout II. 20 A spring I9 secured as by solder at one end to the seat and at the other end to the spout II, tends to retain the seat in the forward position shown. However, when the end I2 of the spout H is inserted into an oil hole, the seat can move 25 along the spout if the pressure exerted by the user is suiicient to compress the spring I9.

The face 28 of the seat I8 is somewhat conical in shape so as to effect a slight radial compression of the sealing member 2| about the spout 30 end I2 to prevent leakage of oil between the spout and gasket as the latter is pressed by the user against the margin of an oil hole.

By the flexible mounting of the sealing member provided by this form of the invention, the end of the spout may be inserted at varying distances in the oil hole and the sealing effect at the margin of the hole satisfactorily attained.

In all the forms of the invention above described, it will be noted that the lower ends of the seats are tapered, which will prevent the seats engaging obstructions or parts of the machine being lubricated upon the withdrawal of the spout from inverted position. 45

It Will also be noted that the forward or free ends of the spouts preferably project a short distance through the respective seats and sealing members and as the ends of the spouts enter the oil holes, they effect the centering of the 50 sealing member with respect to the holes. By exerting slight pressure on the cans before depressing the bottoms to expel the oil, the yielding gaskets or sealing members will seal the oil openings and thus not only prevent waste of lu- 55 bricant but cause the same to be orced more effectually toy the parts to be lubricated.

While I have shown and described. certain emi bodimerntsv of my improvements for the purpose of illustration, I 'do not Wish to be restricted specically thereto except as solimited by the appended claims.

I claim: Y

AnffY oil canL comprising a discharge spoutii having Za non-stretchable rannular supporting member? positioned thereon andY through whichE the endof said spout extends and a flexible seal-fi ing meniber secured to the forward face of said"Y supporting member, said end of said spout coni stituting means'for effecting the registrationV of said sealing member with an oil opening. f i

2. An oil can'comprising a tapered discharge spout, a non-stretchable supporting member provided with a complementary tapered bore tting 20 on said spout adjacent the free end thereof, and

' anV annular sealing member of iiexible material carried by the forward end of said supporting member for sealing an oil opening into WhichtheV end of the spout is inserted. Y e

3. An oil can comprising a discharge spoil having a reciprocableV annular sealing member concentrically positioned thereon, and a spring on said spout for resisting movement of said member in a direction'avvay from said end.

4. An oil can comprising a discharge spoilt having an annular sealing member slidably positioned thereon adjacent the free end thereof, Y a seat for said member provided with a conicalv ,supporting surface adaptedto effect Vthe radial compression of said memberY about said spout upon the exertion of pressure axially of said member, and a spring on saidspout for resisting
